Acquia, which runs a commercial business around open-source Drupal content management technology, moved from Burlington, Mass. to the heart of Boston’s financial district last fall, and finally held its gala grand opening reception Thursday. The space offers lots of natural light, the usual snacks, and the open office plan that is all the fashion for tech companies these days.

Speaking at the grand opening of the space at 53 State St. (aka Exchange Place), Walsh—a politician after all— touted Imagine Boston 2030, which is his plan to build affordable housing; foster open space; and improve mass transit. One goal is to make sure businesses find Boston hospitable, and that at least some of the tens of thousands of college students who graduate from area schools each year can actually afford to stay in the area. Not mentioned was the controversial plan for Boston to host the 2024 Summer Olympics, which Walsh backs.

Companies use Drupal to create and maintain their web sites, marketing collateral and other materials. The company competes with Adobe Systems ADBE, WordPress and Pantheon, and its customers include Mercedes-Benz, Harvard University, Pearson, Al Jazeera, Red Hat RHATand the National Institutes of Health.

But back to the Mayor: At the event, Walsh reiterated his pledge to add 53,000 new affordable housing units by 2030 and put the word out that tech businesses are more than welcome to set up shop in the hub, and affordable housing and a working transit system are key to that. Given the

horrific performance of the mass transit system last winter, it’s clear the city and state agencies have their work cut out for them to meet these goals.

Still, Walsh focused on the positive:

“You will stay here in this building,” he told the crowd of several hundred Acquia employees, investors, and media. “If you take over enough space you can put your name on the top.”

An Acquia exec pointed out that Walsh’s campaign web site was built on Drupal, which apparently was news to Walsh. “I didn’t know that till just now,” he said.

Got bitcoins to spend? Here are some options

Expedia has become the latest company to legitimize the bitcoin craze.

On Wednesday, the travel site said it will start accepting the digital currency for hotel bookings, joining a growing list of well-known retailers and companies now accepting bitcoins. Coinbase, a third-party bitcoin payment processor, works with over 32,000 businesses that accept the digital currency, including Expedia.

While there are the expected online niche businesses accepting bitcoin, such as Reddit and 4Chan, more and more mainstream companies are starting to consider it as a payment option. Apple recently updated its application developer guidelines to pave the way for future bitcoin acceptance, and EBay’s CEO said recently the company is considering adding the option to its namesake auction site and PayPal.

Even tracking the value of bitcoin has reached the mainstream this year. On its eponymous terminal, Bloomberg integrated bitcoin tracking in April, offering live exchange information. Meanwhile, everyday bitcoin investors can turn to Mint.com where the site will track the investment alongside 401(k) and IRA accounts.

Once you’ve got a good handle on the value of your digital holdings, here are just some of the many places you can spend your hard-earned bitcoins.

Buy more than illegal substances.

Overstock.com started accepting bitcoin in January and after 50 days sales using the digital currency surpassed $1 million. More than half of all customers paying with the digital currency were new to Overstock.

Etsy has 500 vendors that are part of the bitcoin vendors group, indicating that the sellers accept the digital currency for their DIY creations. Adding “bitcoin” to the site search brings up even more vendor options.

Get the news.

Chicago Sun-Times, the 167-year-old newspaper, will take your digital payments for its print or online subscriptions.

The NBA’s Sacramento Kings and MLS’ San Jose Earthquakes are two sports teams that accept bitcoin for ticket purchases, gear and, for the Quakes, even a churro or beer at the stadium.

Make a donation.

The Federal Election Committee approved bitcoin for political campaign contributions. Congressman Jared Polis’ campaign was the first to start soliciting donations using the digital currency and has processed more than $1,000 worth of bitcoin since the May debut.

Hitch a ride.

Virgin Galactic welcomes bitcoins for its commercial space flights. “Virgin Galactic is a bold entrepreneurial technology,” Sir Richard Branson told CNBC. “It’s driving a revolution. And bitcoin is doing just the same when it comes to inventing a new currency.”

Do serious business.

Wedbush Securities, a leading financial services provider, accepts bitcoin payments for its research coverage.

TechCrunch opened up an option to attend its recent Disrupt Conference by using the digital currency to cover the nearly $3,000 general admission fee.

And many more.

WordPress, OkCupid, Zynga and Cheapair.com are also all on board with bitcoin payments.

Exclusive: Automattic seeking to raise more than $100 million

FORTUNE — Automattic, the company that runs blogging platforms WordPress.com and WordPress VIP, is out raising between $100 million and $150 million in new venture capital funding, according to multiple sources familiar with the situation.

The round values the company at more than $1 billion and would be a slight step up from its valuation in September 2013. At the time, Tiger Global Management and Iconiq invested $75 million in a secondary transaction, which was mostly used to buy a portion of shares from early investor Polaris Partners. Just a few months prior, Tiger had invested $50 million in a separate secondary round.

But this deal would be new equity, adding to Automattic’s $30.6 million in total equity funding. Automattic declined to comment on any fundraising activity.

WordPress now powers 22% of the world’s websites, up from 19% last July. For example, around half of the sites hosted by GoDaddy are powered by WordPress. Automattic offers a layer of services on top of WordPress, and has introduced curation and editorial elements into its platform. The company employs four editors and is defending its users against take-down notices under the Digital Millennium Copyright Act. Last week, Automattic acquired content site Longreads

Company founder Matt Mullenweg took the helm as CEO in January, after previously serving in a product-centric role. In an interview with Fortune several weeks ago, Mullenweg said his transition was always planned, as he had wanted to be older and more experienced before making the switch (he’s now 30 years old).

Expect that Automattic would use some of the new funds to fend off challenges from rivals like Squarespace, which today announced $40 million in new funding from General Atlantic (bringing its total funds raised to $78.5 million). Or Medium, the blogging platform led by Twitter co-founder Ev Williams.
